Turning the Unit On
Press and hold the Right Key for 3 seconds, until the
LCD displays “on”, the buzzer beeps, and the green
LED is on. After power on, the unit enters a warm up
and self-test sequence, followed by normal mode.
Once in normal mode, the unit will run continuously
until the remaining life time ends, and cannot be
turned off.
Normal & Alarm Modes
In normal mode, the unit continuously monitors the
gas concentration, while the LCD displays the
remaining life time, as long as there is no gas alarm.
If an alarm concentration is exceeded, the LCD
shows either “Low Alarm” or “High Alarm”, depending
on which level is triggered.
